The sE7 is a high-quality back-electret small-diaphragm condenser microphone intended for a wide range of studio and live sound applications, from acoustic guitars to pianos to drums and beyond. It is super quiet, offers a super clear sound, comes equipped with a pad and high pass filter, and comes in all-metal housing for durability. It is a great pencil microphone with a low price tag but punches way above its weight.
